The front yard of a home in central Bismarck, N.D., displays yard signs supporting the re-election of Democratic President Barack Obama and Vice President Joe Biden, as well as the races of North Dakota Democratic U.S. Senate candidate Heidi Heitkamp and Ryan Taylor, the North Dakota Democratic candidate for governor, on Wednesday, Oct. 17, 2012. A lawsuit filed in federal district court in Bismarck, N.D., this week attempts to invalidate a state law that would require that the signs be taken down before midnight on the eve of Election Day, Nov. 6, 2012. The law bans campaigning on Election Day, and the lawsuit alleges the statute violates the free-speech rights of North Dakotans. (AP Photo/Dale Wetzel)
